Project settings apply to the current project only. They are stored together with other project files in the .idea directory in the .xml format. For example, projects keep VCS settings, code style spellchecker settings, the list of language injections, and so on. These settings are placed under version control automatically together with your application code when you send it to your VCS.
To configure project settings, selectfor macOS (Ctrl+Alt+S) or for Windows and Linux.
In the Settings/Preferences dialog, settings that are marked with the icon apply only to the current project. Other settings are global and apply to all existing projects.
If you want to share project settings between already existing projects, you can use the Settings Repository or the Settings Sync plugin. You can also export the settings to a ZIP archive and import it later to other IDE instances.
For the detailed description of every option in the settings, refer to Settings/Preferences dialog.
